Am rebuilding the driveline of a local A/Mod car that ran LS7 074 alloy head BBC back in 1974. Car was 3700lbs usually with 4.56 (12 Bolt also ran a Hone OD ) Car track raced with dual 660s but street raced ( he was a BAAAD boy )with Weiand intake and a 780 vac.
Reason was that it produced better torque out of the hole, and with 3700 lbs it was a factor.
850DPs were made for the Vette A Prod wars with the Cobras.
Great carb but originally designed for the race track (read one with corners )
There is a school of thought, that the the bigger the carb, the better the carb, but ain't always so.
